A: Recent research suggests that a hepatic (liverwort) species traps protists (you know,
protozoans). Whether it digests them has not been demonstrated. The liverwort species responsible
is Colura zoophaga, from Kenya, Africa. It is a tiny liverwort which lives on
the twigs of Cliffortia nitida (Rose family). It traps the ciliate protist
Blepharisma americana.
